Why do we need light to see objects?

• Because light creates objects

• Because light reflects off objects into our eyes

• Because light absorbs objects

• Because light destroys darkness

What happens when light hits an opaque object?

• It disappears

• It changes color

• It creates a shadow

• It passes through the object

How does light help us distinguish colors?

• By creating new colors

• By changing the color of objects

• By reflecting different colors from objects

• By absorbing all colors

What did Isaac Newton prove about white light?

• It is made up of all other colors

• It cannot be split

• It is a single color

• It is not visible

What is the phenomenon called when light splits into a spectrum?

• Dispersion

• Refraction

• Reflection

• Diffusion

How do water droplets create a rainbow?

• By blocking sunlight

• By absorbing sunlight

• By reflecting sunlight

• By spreading sunlight into a spectrum

What is the role of a prism in Newton's experiment?

• To absorb light

• To reflect light

• To change the color of light

• To separate light into different colors

Why do we see a red object as red?

• It emits red light

• It absorbs red light

• It reflects red light

• It changes color to red

What happens to the other colors when we see a red object?

• They are emitted

• They are absorbed

• They are changed

• They are reflected

How do objects of different colors affect the spectrum of light?

• They absorb all colors

• They emit new colors

• They reflect their own color

• They reflect all colors equally
